i just have to ask..

is this practiced by most jews or confined
to a secret "order" of them?

just looked up the talmud and saw this:

Primary source of Jewish religious law??

in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations"

The Talmud (/ˈtɑːlmʊd, -məd, ˈtæl-/; Hebrew: תַּלְמוּד‎, romanized: Talmūḏ) is the central text of Rabbinic Judaism and the primary source of Jewish religious law (halakha) and Jewish theology.[1][2] Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.[3]
